BP Biofuels

In Brazil, this unit of British oil giant BP (BP) is making ethanol the old way, from sugarcane. But the company is also investing $500 million over the next 10 years to find new applications for bioscience in the energy industry. Projects range from a biobutanol plant in Hull, England, to a project in India exploring biodiesel from jatropha, an oilseed-bearing tree.
